To @ZZ whom it muy concern:

Be it known that I, MILES V. HAETONG, a citizen of the United States,residingl at Plainfield, in the county of Will and State of Illinois,have invented a new and useful Windmill, of which the following is aspecification.

This invention relates to improvements in windmills, and has for itsobject to improve the construction and increase the eiciency of devicesof this character.

With this and other obj'ects in view, which will appear as the nature ofthe invention is better understood, the inventionconsists in certainnovel features of construction, as hereinafter fully described andclaimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designating characters,is illustrated the preferred form of the embodiment of the inventioncapable of carrying the same into practical operation.

In the drawings, Figure 1 is a side elevation, partly in section, of theimproved apparatus with one of the wings removed. Fig. 2 is a plan viewpartly in section. Fig. 3 is a section on the line 3 3 of Fig. 1.

The improved device may be erected upon any suitable structure, such asa tower, the roof of a building, or the like, which will elevate itsufficiently to receive the full force of the wind, and for the purposeof illustration is shown mounted upon a tower structure, (represented at10.)

The improved device comprises a baseframe 11, adapted to be rigidlyconnected to the supporting structure-as, for instance, the tower 10-andwith a vertical shaft 12, rotatively supported therein.

. A collar 13 is disposed upon the upper surface of the frame 11 andsurrounding the shaft 12 and provided with an annular channel forreceiving bearing-balls 14, and the shaft 12 is provided with acorresponding collar 15, having an annular channel bearing over theballs 14, the two collars with their channels and the bearing-ballforming an efflcient ball-bearing connection between the shaft andframe. v'At the lower end of the frame the shaft 12 is further supportedby a bearing 16, the relatively elongated baseframe thus providing acorrespondinglyelongated supportto the shaft and eifectually preventingdisplacement by the action of the Wind against the the upper end of theshaft.

Rigidly connected to the upper end of the shaft 12 is a hub 17, havingradiating arms 18, and rigidly connected to the shaft above the frame l1is a hub 48, having radial arins 49 and rim 19 and spaced from the hub17 and its arms 18. The wings or sails of the mill are disposed betweenthe arms 18 and rim 19.

The wings or sails of the improved structure vherein described are ofnovel construction, each consisting of an outer curved segmental plate20 and an inner curved segmental plate 21 of a greater radius than theouter curved plate, so that when the two plates are united at theiredges 47 they form a crescent-shaped structure, as represented in Fig.2.

The crescent-shaped wings are closed at the ends and provided interiorlywith suitable braces (indicated at 22) at intervals.

The terminals of the arms 18 are provided with bearings at 23, and therim 19 is provided with corresponding bearings at 24, the two sets ofbearings 23 24 being disposed in vertical alinenient and adapted toreceive studs 25 26, extending from the ends of the wings, the wingsbeing thus mounted to swing between the arms 18 and rim 19. Any numberof arms 18 and wings 20 21 may be employed, the number depending uponthe size of the mill but for the purpose of illustration four of thearms and a corresponding number of Wings are shown.

The curved wings will be so propotioned relative to the lengths of thearms 18 and the size of the rim 19 that when in closed position, asindicated by dotted lines in Fig. 2, the wings will interfold to formsubstantially a cylindrical structure against which the wind will not beeffective. On the other hand, when the curved wings are distended or inopen position, as shown in full lines in Fig. 2, they present arelatively large area to the wind, which rapidly rotates them and thearms, frame, and shaft associated therewith and produces an effectiveand powerful windmill structure.

YA simply-constructed automatic governor apparatus is attached `to thedevice and a simply-constructed means for throwing the wings into andout of the wind, and thus controlling the speed or entirely stopping themotion, as may be required.

windmill structure upon IIC The governor mechanism consists of aplurality of substantially vertical levers 27, one for each ofthe wingsand each pivoted intermediate its ends at 23 to standards 29, risingfrom the arms 49, the upper ends of the levers being coupled by rods 30to the wings at a short distance from the vertical lines of the studs 2526 and the lower ends of the levers extending below the arms 49 and eachprovided with a weight 31, the weights adjustable upon the levers byset-screws32.

The relative positions of the levers 27 and the lengths of the rods 30will be so arranged that when the levers are held in vertical positionby the gravity of the weights 31 the wings will be supported in theirextended or outward position, as shown in full lines in Fig. 2,-andwhile the motion is normal the weights will produce no effect upon thewings; but any abnormal increase of speed will cause the weights to bemoved outwardly by centrifugal force, and thus draw the wings inwardlyand decrease the area presented to the wind and correspondinglydecreasing the speed, the weighted levers thus serving as effectualautomatic governors to the wings to control the speed and insure theuniformity of the motion. The weights 31 being adjustable verticallyupon the levers 27, the force exerted thereby may be easily control-led,as will be obvious.

Slidably disposed upon the shaft 12 are two disks 33 34, spaced apartand connected by a shell 35, the disks and shell rotatable with theshaft, but movable longitudinally thereon over a feather 36 on theshaft.

Extending from each of the levers 27 is a lateral arm 38, and pivotedtothe free ends of the arms are rods 39, the latter extending through theplate 19 and coupled to the disk 33, so that the vertical movement ofthe disk upon the shaft will be communicated to the levers 27.

Extending through the frame 1 1 are spaced rods 40 4l, having rollers 4243, extending between the disks 33 34, the rods being supportedyieldably in their upward position by springs 44 45,' bearing at theirlower ends upon the bottom members of the frame 1 1.

The rods 40 41 are connected at their lower ends to a fiexible element,such as a chain, (represented at 46,) convenient to the hand of theoperator. The rods 40 41 will be supported by the springs 44 45 normallyin upward position or with the rollers 42 43 out of engagement with thedisk 34, the space between the disks 33 34 being sufficient to permit aconsiderable vertical movement of the disks and the connecting-shell 35without comi-ng in contact with the rollers 42 43. Thus the presence ofthe disks 33 34 and connecting-shell 35 and their connections to thelevers 27 does not interfere with the automatic operation of thegovernor mechanism under the control of the weights 3 1; but when it isrequired to throw the wings out of the wind mechanically this canquickly be accomplished by simply drawing downwardly upon the-chain 46,which action causes the rollers 42 43 to bear upon the disk 34 anddepress the rods 39 and cause them to forcibly operate the levers 27 anddraw the wings inwardly and dispose them in their cylindrical form, asshown by dotted lines in Fig. 2. The wings are thus under the completecontrol of the operator, who can easily set the wings at any desiredpoint by simply fastening the pull-chain 46 at any desired point,

and thus hold the rollers 42 43 in contact with the disk 34 or withdrawthe wings entirely from the influence of the wind, as may be desired.

The apparatus is simple in construction, strong and durable, may beinexpensively manufactured and of any suitable material, size, orcapacity, and operates effectually for the purposes described.

Having thus described the invention, what is claimed as new isd 1.
